AP Calculus Review: Finding Absolute Extrema - Magoosh

WebTo obtain the extrema of a function in a closed interval, we must first find the critical numbers of f f f in the interval (a, b) (a,b) (a, b), and then evaluate the function at the critical numbers.We then evaluate the function at the endpoints as well. The greatest of the various values will be the maximum and the least of them will be the minimum. WebAbsolute Extrema Consider the function f(x) = x2 + 1 over the interval ( − ∞, ∞). As x → ± ∞, f(x) → ∞. Therefore, the function does not have a largest value. However, since x2 + 1 ≥ 1 for all real numbers x and x2 + 1 = 1 when x = 0, the function has a smallest value, 1, when x = 0.
